Hi Xi,
I don't want to dampen your enthusiasm at all, however, there is one aspect about which you should be aware if you arn't already. That being that the ginseng in one area is not always the same as the ginseng in another area. Assuming larger, mature, well handled roots with sufficient age as we move forward speaking in overarching generalities.
I am in Ohio and relate most things to our root here. Our root from the southeastern part of the state is normally the better stuff we see. There is some very nice stuff all up the eastern side and along the Ohio River at the bottom of the state. Certainly there is some good stuff everywhere, but not in the average lot you see a digger bring in. Prices quoted for Ohio will normally be for higher quality root in the state. Not all of the root in the state will have the same quality, however.
Just as the quality of the best roots are different within the state of Ohio, the nature and quality of the roots from different parts of the country are different also. For instance, Ohio normally values $150-200 over Kentucky and most of the root from Tennessee, W Virginia and Virginia. However, we are normally $200 behind N Carolina and New York. Some of the states up in the northeastern part of the country consistently produce some exceptional roots as you can see here on the forum. These might not be average roots for that section, but there are more of them coming from there than other places. This is why Ohio might be $300 behind Vermont.
So while your thoughts are logical, (and I think they were influenced by someone who is being less than honest) that being taking root from one area to a dealer in another area where they pay higher prices, it won't work in reality because the root you are taking isn't the same type of root for which they are paying that kind of money. Also keep in mind that most dealers don't operate outside of their home state, and the certification laws make doing so very difficult.
Always remember, the high end ginseng market is always about quality over quantity.
